Abstract
In the course of the purification procedure of pyoverdins produced by Pseudomonas aeruginosa ATCC 15692 in large batch cultures, a minor pep tidic chlorinated, siderophore was isolated. This compound possesses t he some peptidic moiety as the three major pyoverdins isolated from th is strain, but it is bound to a chlorinated chromophore derived from 5 -chloro-2,3-diamino-6,7-dihydroxyquinoline. A mechanism for the format ion of these compounds is suggested and a procedure for the preparatio n of halopyoverdins is described. Copyright (C) 1996 Published by Else vier Science Ltd
